bktr problems.

I have an odd problem with the bktr driver. When I launch fxtv, the
video display is extremely jerky. It isn't till I cover a small
segment of the window (just has to be a pixel or two) till the video
starts displaying normally.
fxtv displays the following error message:
ioctl(METEORSSIGNAL, -65536) failed: Invalid argument
ioctl(METEORSSIGNAL, -65536) failed: Invalid argument
TVSCREENStartVideo called with continous capture already

And so on and so forth.
Under FreeBSD 5.2-CURRENT, I have no such problems. However I've
noticed that a number of ports (such as ffmpeg) don't build under
5.2-CURRENT without modifying some of the applications headers to point
to the correct (and apparently new) ioctl_meteor.h and ioctl_bt848.h
headers in the source tree.
Anyone know how to fix this little problem? :-)
